Sorry, you need a Java-enabled browser to see the simulation.

<p>
This filter passes a range of frequencies
close to the resonance frequency of the LC pair (shown at the lower
right).  When it gets
  close to the <a href="e-res-par.html">resonance frequency</a>,
the impedance
of the LC pair increases, keeping the output closer to the input.
You can click on the frequency response graph to see
the circuit in operation at that particular frequency.
